RFR: 8160518: Semicolon is not recognized as comment starting character (Kerberos)

[Ivan Gerasimov]

Hello!

We've got a complain that a semicolon character cannot be used to start 
a comment in the kerberos config file.
In the documentation [1] I don't see mentioning comments at all, but it 
is said that the config file is in style of Windows INI file, and the 
later does allow semicolons to be used.
This blog entry [2] also mentions the semicolon as an alternative to the 
hash sign '#'.

Would you please review the trivial change?
Comments, suggestions are very welcome.
